Description

Technical Field

[0001] The invention relates to the field of medical devices, and in particular to an automatic following system for an infusion set for children. Background Art

[0002] Currently, hospitals generally perform infusion by hanging the medicine bag on an infusion stand, and the infusion stand is either fixed on the infusion chair or next to the chair.

[0003] The existing intelligent assisted drip device can provide convenience of movement for patients receiving intravenous drips. It can move automatically and follow the patient without pushing with hands. By setting up a support arm and an induction sensor, the stability of the infusion hand is maintained during the movement, thereby avoiding the risk of needle rolling.

[0004] However, when the existing intelligent auxiliary drip device is used for children, the children are prone to leave the safe area. When leaving the safe area, they are prone to collide with other patients in the aisle and cause safety accidents. Summary of the invention

[0005] One object of the present invention is to provide an automatic following system for an infusion set for children, so that a drip support mechanism can only move in a safe area, thereby preventing children from leaving the safe area.

[0006] This purpose is achieved by adopting the following technical solutions:

[0007] An automatic following system for an infusion set for children includes a drip support mechanism, an automatic walking mechanism and an auxiliary control module; the drip support mechanism includes a support rod and a support arm, the support rod is arranged on the automatic walking mechanism; the support arm is arranged on the support rod. When in use, the child's hand is placed on the support arm of the drip support mechanism, the infusion bottle is hung on the support rod, and the automatic walking mechanism drives the support rod of the system to move.

[0008] Wherein, the auxiliary control module is arranged on the automatic walking mechanism, and the auxiliary control module includes a speed adjustment module, a position information module and a judgment module; the position information module is used to obtain the position information of the dripping support mechanism; the judgment module is used to obtain the distance between the dripping support mechanism and the edge of the safety area according to the position information of the dripping support mechanism; the speed adjustment module is used to adjust the moving speed of the automatic walking mechanism according to the distance between the dripping support mechanism and the edge of the safety area;

[0009] When the distance between the drip support mechanism and the edge of the safety area is less than a first preset value and greater than or equal to a second preset value, the speed adjustment module slows down the speed of the automatic walking mechanism to the first preset speed;

[0010] When the distance between the drip support mechanism and the edge of the safety area is less than the second preset value and greater than or equal to the third preset value, the speed adjustment module slows down the speed of the automatic walking mechanism to the second preset speed;

[0011] When the distance between the drip support mechanism and the edge of the safety area is less than a third preset value, the speed adjustment module slows down the speed of the automatic walking mechanism to 0; wherein the first preset speed is greater than the second preset speed.

[0012] When the system is in use, the speed of the automatic walking mechanism is initially driven by the patient, and the speed of the automatic walking mechanism is adjusted as the patient's moving speed changes. When the distance between the drip support mechanism and the edge of the safety area is less than a first preset value, the speed of the automatic walking mechanism begins to decrease at a preset frequency and will not suddenly decrease to 0, thereby avoiding a sudden and substantial deceleration of the automatic walking mechanism, which may cause the patient to fall.

[0013] Preferably, the first preset value is 15 meters, the second preset value is 12 meters, and the third preset value is 8 meters. This further avoids the patient from falling due to a sudden change in speed.

[0014] Furthermore, when the distance between the drip support mechanism and the edge of the safety area is less than the second preset value and greater than or equal to the third preset value, the position information module obtains the position information of the drip support mechanism and sends the position information of the drip support mechanism to the nurse end; the drip support mechanism triggers the alarm component to issue the first alarm.

[0015] When the distance between the dripping support mechanism and the edge of the safety area is less than a third preset value, the position information module obtains the position information of the dripping support mechanism and sends the position information of the dripping support mechanism to the nurse end; the dripping support mechanism triggers the alarm component to issue a second alarm.

[0016] The alarm is used to remind the patient that he is about to leave the safe area. The first and second alarms are issued to the patient before the speed of the automatic walking mechanism is reduced to 0, reminding the patient to turn back in time to avoid the speed of the automatic walking mechanism being reduced to 0, thereby avoiding safety accidents.

[0017] Furthermore, child patients have no self-control, and even if there are alarm reminders, it may not necessarily prevent the children from leaving the safe area. Therefore, the auxiliary control module also includes a moving module and a route prediction module. The moving module is used to obtain the current speed information and moving direction information of the automatic walking mechanism; the route prediction module divides the safe area into several working areas; the route prediction module determines whether the drip support mechanism will leave the safe area based on the position information of the drip support mechanism, the current speed information and moving direction information of the automatic walking mechanism. If the drip support mechanism will leave the safe area, the route prediction module sends the position information of the drip support mechanism to the staff in the working area where the drip support mechanism is located.

[0018] Among them, judging whether the drip support mechanism will leave the safe area specifically includes:

[0019] The route prediction module obtains the distance between the drip support mechanism and the edge of the safety area in the current moving direction of the automatic walking mechanism;

[0020] The route prediction module obtains the time required for the dripping support mechanism to move the distance between the dripping support mechanism and the edge of the safety area in the moving direction according to the current speed information of the automatic walking mechanism;

[0021] If the required time is greater than or equal to the preset time, it is determined that the drip support mechanism will not leave the safety area;

[0022] If the required time is less than the preset time, it is determined that the drip support mechanism will leave the safe area.

[0023] Preferably, the preset time is 3 minutes.

[0024] Through the route prediction module, the staff in the corresponding work area will bring the patient back before the patient leaves the safe area, preventing children from leaving the safe area.

[0025] On the other hand, the automatic walking mechanism includes a base, and a plurality of anti-fall plates are arranged on the side of the upper end surface of the base, and a distance sensor is arranged at the lower end of the anti-fall plate, and the distance sensor is used to detect the distance between the lower end of the anti-fall plate and the ground. Each anti-fall plate 7 is provided with a first angle sensor, and the first angle sensor is used to monitor the angle between the corresponding anti-fall plate 7 and the vertical line; when the distance sensor detects that the distance between the lower end of the anti-fall plate and the ground is less than a threshold value, the first angle sensor obtains the angle between the anti-fall plate and the vertical line, rotates the anti-fall plate by a corresponding angle, keeps the anti-fall plate in a vertical state, and extends the lower end of the anti-fall plate to contact the ground.

[0026] A second angle sensor is arranged on the side surface of the upper end surface of the base, and the second angle sensor is used to detect the angle between the upper end surface of the base and the horizontal plane. When the first angle sensor device monitors that the angle between the upper end surface of the base and the horizontal plane is greater than or equal to 45 degrees, the horizontal plane where the center of the upper end surface of the base is located is the interface, and the interface divides the upper end surface of the base into a lower inclined surface and an upper inclined surface, and the lower end of the anti-fall plate on the lower inclined surface is extended to contact the ground.

[0027] When the patient runs or runs too fast, the support rod will tilt. When the support rod tilts, the base will also tilt with it. The base adopts a tumbler structure. When it tilts, it will automatically return to its original position. During the tilting of the base, it can prevent the patient from moving too fast to a certain extent. At the same time, when the base tilts to a certain extent, the support rod rotates to a vertical state and extends to contact the ground, preventing the base from tilting too much and causing the patient to fall, while promoting the rapid recovery of the base.

[0028] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0029] The present invention discloses an automatic following system for an infusion set for children. The system can effectively prevent the patient from leaving a safe area and causing an accident outside the safe area. At the same time, before the patient leaves the safe area, the speed of the automatic walking mechanism is adjusted to prevent the patient from leaving the safe area and to prevent the patient from falling during the deceleration process. At the same time, the system has an alarm component, which can issue a reminder to the patient.

[0030] Children are lively and active by nature, and they often cannot endure long, boring, and activity-restricting infusions. Currently, hospitals only allow one parent to accompany their child, and taking care of the child plus various treatments has already made the parents physically and mentally exhausted. This system not only protects the child's nature but also can appropriately liberate the parents and reduce their care pressure. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary implementation modes of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0039] In the description of the present invention, it should be understood that the terms "front", "rear", "left", "right", "up", "down", "vertical", "horizontal", "high", "low", "inside", "outside", etc., indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the scope of protection of the present invention.

[0040] Example 1

[0041] like Figure 1 As shown, the system includes a drip support mechanism, an automatic walking mechanism and an auxiliary control module; the drip support mechanism includes a support rod 1 and a support arm 5, the support rod 1 is arranged on the automatic walking mechanism; the support arm 5 is arranged on the support rod 1; a slide 4 is arranged on the support rod 1, the support arm 5 is connected to the slide 4, and the support arm 5 can slide up and down along the direction of the slide 4. The automatic walking mechanism includes a base 2, the lower end of the base 2 is provided with a pulley assembly 3, the base 2 is a tumbler structure, the lower end of the support rod 1 is connected to the base 2, and the side of the base 2 is connected with an anti-fall plate 7, when the inclination angle of the base 2 is greater than or equal to 45 degrees, the lower end of the anti-fall plate 7 contacts the ground. A hook 6 is provided on the top of the support rod 1, which can be used to hang a hanging bottle.

[0042] The hospital's infusion area is equipped with a safety zone, and patients receiving infusions can only walk in the safety zone. If there are other patients outside the safety zone, safety accidents may easily occur.

[0043] The auxiliary control module is arranged on the automatic walking mechanism, and the auxiliary control module includes a speed adjustment module, a position information module and a judgment module; the position information module is used to obtain the position information of the dripping support mechanism; the judgment module is used to obtain the distance between the dripping support mechanism and the edge of the safety area according to the position information of the dripping support mechanism; the speed adjustment module is used to adjust the moving speed of the automatic walking mechanism according to the distance between the dripping support mechanism and the edge of the safety area;

[0044] When in use, the patient places his arm on the support arm 5, which fixes the patient's arm. When the patient moves, the arm drives the base 2 and the pulley assembly 3 to move together. When the patient moves too fast, the support rod 1 and the base 2 will tilt. When tilting, the base will drive the support rod to move in the opposite direction due to the tumbler structure, so as to slow down the patient's speed.

[0045] In some embodiments, Figure 2 As shown, the upper end surface of the base 2 is circular, and a plurality of anti-fall plates 7 are arranged on the side of the upper end surface of the base 2. A distance sensor is arranged at the lower end of the anti-fall plate 7, and the distance sensor is used to detect the distance between the lower end of the anti-fall plate 7 and the ground. A first angle sensor is arranged on each anti-fall plate 7, and the first angle sensor is used to monitor the angle between the corresponding anti-fall plate 7 and the vertical line.

[0046] When the distance sensor detects that the distance between the lower end of the anti-fall plate 7 and the ground is less than a threshold value, Figure 3 As shown, the first angle sensor obtains the angle between the anti-fall plate 7 and the vertical line, and rotates the anti-fall plate 7 to a corresponding angle, so that the anti-fall plate 7 remains in a vertical state, and the lower end of the anti-fall plate 7 is extended to contact the ground.

[0047] A second angle sensor is arranged on the side surface of the upper end surface of the base 2, and the second angle sensor is used to detect the angle between the upper end surface of the base and the horizontal plane. When the first angle sensor detects that the angle between the upper end surface of the base and the horizontal plane is greater than or equal to 45 degrees, the horizontal plane where the center of the upper end surface of the base 2 is located is the interface, and the interface divides the upper end surface of the base 2 into a lower inclined surface and an upper inclined surface, and the lower end of the anti-fall plate 7 on the lower inclined surface is extended to contact the ground.

[0048] In some embodiments, when the anti-fall plate 7 is shortened, the length is one third of the height of the base 2 .

[0049] In some embodiments, the anti-fall plate 7 is connected to the side of the base via a gear, and the angle of the anti-fall plate 7 is controlled by adjusting the rotation of the gear.

[0050] In some embodiments, the anti-fall plate 7 is evenly arranged on the side of the base, such as Figure 4As shown, the upper ends of two adjacent anti-fall plates 7 are in contact with each other, and the anti-fall plates 7 are cylindrical.

[0051] In some embodiments, the upper end of the anti-fall plate 7 is hinged to the side of the upper end surface of the base 2, and the anti-fall plate 7 is connected to the side of the base 2 via a telescopic rod. The telescopic rod is adjusted by telescoping the length of the telescopic rod, thereby adjusting the distance between the anti-fall plate and the side of the base, thereby achieving the effect of adjusting the angle of the anti-fall plate.

[0052] In some embodiments, the support arm 5 of the present invention is used to place the patient's arm, and the support arm 5 is used to connect the patient and the system. The site of the patient's infusion can be other parts except the arm, and the present invention does not limit the site of infusion.

[0053] Example 2

[0054] On the basis of the above embodiment, when the distance between the drip support mechanism and the edge of the safety area is less than the first preset value and greater than or equal to the second preset value, the speed adjustment module slows down the speed of the automatic walking mechanism to the first preset speed; the first preset value is 15 meters; the first preset speed is half of the moving speed of the automatic walking mechanism when the distance between the drip support mechanism and the edge of the safety area is less than the first preset value;

[0055] When the distance between the drip support mechanism and the edge of the safety area is less than the second preset value and greater than or equal to the third preset value, the speed adjustment module slows down the speed of the automatic walking mechanism to the second preset speed, the position information module obtains the position information of the drip support mechanism, and sends the position information of the drip support mechanism to the nurse end; the drip support mechanism triggers the alarm component, which triggers the alarm component to issue the first alarm; the second preset value is 12 meters; the second preset speed is half of the moving speed of the automatic walking mechanism when the distance between the drip support mechanism and the edge of the safety area is less than the second preset value;

[0056] When the distance between the drip support mechanism and the edge of the safety area is less than the third preset value, the speed adjustment module slows down the speed of the automatic walking mechanism to 0; wherein the first preset speed is greater than the second preset speed; the position information module obtains the position information of the drip support mechanism, and sends the position information of the drip support mechanism to the nurse end; the drip support mechanism triggers the alarm component, which triggers the alarm component to issue a second alarm; the third preset value is 8 meters.

[0057] The speed regulating module reduces the speed at a preset frequency. The speed reduction at the preset frequency refers to a uniform speed reduction. The preset frequency refers to the slope of the speed in a curve of speed and time.

[0058] Example 3

[0059] Based on the above embodiment, the auxiliary control module also includes a moving module and a route prediction module. The moving module is used to obtain the current speed information and moving direction information of the automatic walking mechanism; the route prediction module divides the safety area into several working areas; each working area has corresponding staff.

[0060] The route prediction module determines whether the dripping support mechanism will leave the safe area based on the position information of the dripping support mechanism, the current speed information and the moving direction information of the automatic walking mechanism. If the dripping support mechanism will leave the safe area, the route prediction module will send the position information of the dripping support mechanism to the staff in the working area where the dripping support mechanism is located.

[0061] Determine whether the drip support mechanism will leave the safe area, including:

[0062] The route prediction module obtains the distance between the drip support mechanism and the edge of the safety area in the current moving direction of the automatic walking mechanism;

[0063] The route prediction module obtains the time required for the dripping support mechanism to move the distance between the dripping support mechanism and the edge of the safety area in the moving direction according to the current speed information of the automatic walking mechanism;

[0064] If the required time is greater than or equal to the preset time, it is determined that the drip support mechanism will not leave the safety area;

[0065] If the required time is less than the preset time, it is determined that the drip support mechanism will leave the safe area. The preset time is 3 minutes.

[0066] Generally speaking, it is not easy for child patients to change their moving direction when walking or running at a fast speed. Therefore, this system uses the current moving direction of the automatic walking mechanism as the later moving route. The distance between the drip support mechanism and the edge of the safe area under this moving direction is the distance that the patient will walk under the current moving direction of the automatic walking mechanism. If the time required for the patient to leave the safe area at the current moving speed is greater than or equal to 3 minutes, it is judged that the patient will not leave the safe area, otherwise. If the drip support mechanism will leave the safe area, the route prediction module will send the location information of the drip support mechanism to the staff in the working area where the drip support mechanism is located. The staff quickly stops the patient from leaving the safe area.

[0067] Example 4

[0068] Based on the above embodiment, the supporting arm 5 is provided with an induction sensor, such as an infrared sensor, for sensing whether the patient's arm is placed there; a camera is provided on the support rod 1, and an identity recognition module is provided on the support rod 1 for identifying the patient's identity information, and the identity recognition module can be a QR code, etc.

[0069] The support arm 5 is provided with an adjustment button for controlling the sliding of the support arm 5 on the slide groove 4. A locking mechanism is also provided in the slide groove 4; the support arm 5 is provided with a locking button for controlling the operation of the locking mechanism. Specifically, the locking mechanism can be locked by an electromagnetic lock. The support arm 5 is also provided with a fixing rope, which fixes the arm on the support arm 5 to prevent the support arm 5 from being separated from the patient's hand.

[0070] When in use, the patient's identity information is identified through the identity recognition module. After confirmation, the system cancels the lock of the automatic walking mechanism, and the automatic walking mechanism can move freely with the patient.

[0071] In the sitting state, the patient places his arm on the supporting arm 5 and adjusts the position of the supporting arm 5 on the slide slot 4 by means of the adjustment button so that the patient can obtain a comfortable placement posture; the supporting arm 3 is locked in the current position by operating the locking button.

[0072] When the patient needs to stand and walk, he first operates the locking button to unlock it, and then adjusts the position of the supporting arm 5 on the slide slot 4 through the adjustment button to obtain a comfortable placement posture when standing.

[0073] The camera obtains the image of the patient's foot as the ROI area, and uses the ROI area as the basis for identification. When the camera recognizes that the patient's foot starts to move, the lock of the automatic walking mechanism is canceled, and the automatic walking mechanism moves under the drive of the patient.

[0074] When the camera recognizes that the patient's feet stop moving, the automatic walking mechanism is locked and stops moving.
